1 Claim. (Cl. 16-10) This invention relates to devices for attaching and holding carpet in place and more particularly to a double duty stair device intended to reduce labor, improve the method of application and preserve the rug or carpet in the process of tackless installation of the rug or carpet.

This invention is intended primarily to be used in fastening tackless carpeting to stairs and consists essentially of a right angle strip constructed in such a man ner that when manufactured it may be nailed to the stair tread and eliminate the necessity of nailing separate strips to the risers. Accordingly, the invention is embodied in a one-piece strip having a pair of walls arranged at rights angles to each other and provided with a number of nails which penetrate the carpet and hold it fast to the tread and adjacent to the risers.

An important feature of the invention is the construction of the lower wall, generally applied horizontal since most stair treads are horizontal or at least, approximately so. This wall has an offset at its inner end with the offset approximately parallel to the vertical wall thereby spacing the horizontal wall from the surface of the tread. This forms, with a part of the surface of the tread, a pocket within which to accommodate the carpet pad and firmly and separately hold the pad fixed in place. Therefore the pad is not necessarily nailed in place and moreover, the pad is much more firmly held beneath the carpet.

These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawing forming a part hereof, wherein like numerals refer to like parts throughout, and in which:

Figure 1 is a fragmentary perspective view of a typical stair that is carpeted with the carpet held in place by a strip in accordance with the invention.

Figure 2 is a fragmentary perspective view of the strip in Figure 1.

Figure 3 is an enlarged fragmentary sectional view taken on the line 3-3 of Figure 1.

In the accompanying drawings there is a strip which exemplifies the invention. This strip is preferably made of light weight metal and is approximately two and onehalf inches in width and having a proposed length of 27 inches. However, it is to be clearly understood that both the width and the length may vary.

Strip 10 has two walls 12 and 14 at right angles to each other. Wall 12 is intended to be placed flush against the front surface of the riser, for example riser 16 of a Wall 14 is approximately parallel to but spaced from the upper surface of the tread 18. Both walls have a plurality of pins 20 which can be fixed in place by spot welding, brazing or by any other method. The pins 20 protrude forwardly of the front surface of the wall 12. The pins or nails 20 on wall 14 rise upwardly from the surface of the wall 14. This is to have a firm anchorage 2,958,895 Patented Nov. 8, 1960 in the carpet with the anchorage constituted by the nails 20 penetrating the carpet and ,being at an angle to each other as shown in Figure 3. This interlocks adjacent portions of the carpet on the strip 10. Wall 14 has an offset 24 at its inner edge, the offset consisting of a short wall that is approximately perpendicular to the main area of wall 14 and that isv approximately parallel but spaced, by spacing portion 26 ofwall 14, from wall 12. The front surface of wall 24, the bottom surface of wall 14 and a part of the top surface of tread 18 constitutes a pocket 28 within which to accommodate the edge of the pad 30 of the carpeting.

The channel 28 also lends itself to facilitate the seamless joining of separate pieces of carpet by inducing the terminal end of each piece or strip of carpet into the channel and securing the carpet in place after it is pierced by the pin 20.

In installing the carpet, pad 30 is slipped into pocket 28 and when the strip 10 is nailed in place, the anchoring nails 32 that pass through precut holes 33 in wall 14, also pass through the pad 30 holding it firmly fixed in place. Thereafter the carpet 34 or rug is fitted in place and empaled on nails 20. This completes the carpet installation insofar as the described tread 18 is concerned, the procedure being repeated for each tread.

In installing carpet 34 the suggested procedure would be to have the carpet drawn over the tread of the step and continuing to draw it above the riser in its appropriate final position. The portion of the carpet in which the angle would be formed is then drawn taut and pressed into the upwardly opening channel 38 that is formed by the inside surfaces of portion 26, wall 24 and the opposing part of wall 12'. A dull curved tool can be used for this and when the tool is withdrawn the anchor nails secure the carpet or rug in place. This process is repeated on each step until the installation has been completed throughout the stairway.

It is important to note that pocket 28 accommodates the pad 30 holding it firmly fixed with the fastening being independent of the fastening for carpet 34. Secondly, the upwardly opening channel 38 forms another pocket within which to accommodate a part of the carpet While it is being empaled on the nails. This is a very rapid and exceedingly effective way of anchoring the carpet at the junction of the treads 18 and risers 16.

The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention as claimed.

What is claimed as new is as follows:

For use in anchoring a carpet and its pad to a stair having at least one tread and at least one riser disposed at substantially right angles to said tread, an anchoring strip having a vertical first wall adapted to abuttingly engage the front surface of said riser in surface to surface containing relation therewith, a horizontal second wall, means connecting said first and second walls with said second wall spaced from and projecting at substantially right angles to said first wall in a plane passing through said first wall above the lower end thereof, said connecting means including an offset wall portion carried by the end of said second wall adjacent said first wall depending from and disposed at substantially right angles to said second wall and terminating in a lower end portion curving into the lower end of said first wall, the lowermost portion of said offset wall portion adapted to abut the tread and position said second wall a spaced distance thereabove thereby defining a pocket between said tread and second wall opening outwardly away from said riser in which an end edge of said pad is received, said strip including means for simultaneously anchoring the strip to the tread and the pad to the tread and in said pocket, a plurality of impaling members projecting from the adjacent surfaces of said first and second walls and adapted to engage portions of a carpet disposed thereover, said offset wall portion formed integrally with said first and second walls, the confronting surfaces of said oifset wall portion and said first wall defining an upwardly opening pocket for receiving therein portions of a carpet disposed between those portions of the carpet overlying said first and second walls.
